snow-annovme MACHINE Application led May 29, 1926, Serial No. 112,661. Renewed July 24, 1928.

This invention relates to a machine forremoving snow. Y

Many types of snow removing devices have been designed, but mostot them are very complicated in construction and in operation, and they are expensive to manufacture. This invention has forits salient object to provide a simple and practical device of the character described that can be economically manufactured.

Another object of the invention'is'to provide a snow removinglr device that can be easily and quickly attached to a motorvehicle and can be operated from the power shaftof the vehicle.

Further objects of the invention will appear from the following specification, taken in connectionwithk the drawings .which form part or this application, and in which y n Fig, 1 is a top plan view of a machine constructed in accordance with this invent-ion;

Fig. 2 is a front elevation of the device shown in Fig. 1;

Fig. 3 is an elevational'viewshowing the means for the frame of the attachment;

Fig. .4 is an elevational view showing the connection between one Aof the links and one of the slats; f K

Fig. 5 is a view taken at right anglesr to Fig. 4; i

Fig. 6 is a sectional det-ail view showing theV connection between one of, the slats andone i of the chain links; and Y Y f Fig. 7 is a sectional detail View showing the supporting ledge for the conveyor chains;V

The invention briefly described, consists of an attachment adapted to be secured to -the front of a motor vehicle, and'having operative parts vadapted, to be driven from the power shaft of the vehicle'. V i

The attachment comprises aLfrarneadapted to extend -transversely across 4the front of the vehicle and a pair-of endless chains arey mounted on,y the frame having secured thereto transverse slats. The chains are driven from the power shaft ofthe vehicle and the slats are moved with the chains across the path of thel vehicle and scrape or-push the snow laterally to oneside of the machine.

Further details of the invention will appear from the following specification.

In the embodiment of the invention illustrated, the device Ais shown as secured to the front end of' a motor vehicle 10. The vehicle has secured thereto a supplemental frame having longitudinally extending frame members 11 and 12 securedto the front end of the vehicle frame 13. The frame members 11 and 12 have pivotally connected thereto at 14 and '15 longitudinally extending frame members 16 and 17, the rear ends of the members 16 and 17 being disposed beneat-h'stop-lugs 18 and 19. It will thus be seen that the members 15 and 16 can be tilted upwardly about Vtheir pivots 14 and 15 but that their Vdownward movement is limited bythe stops 18 and 19.

The front ends of the members 16 and 17 have secured thereto a box-shaped frame comprising a bottom20, a top 21, and ends 22 and The various parts are braced by truss members 24, 25, 26 and 27 The boxshaped frame has vertically extending Struts or posts 3() and 31 which'are secured to the members 16 and 17 and support the boxshaped frame thereon. i

There is also mounted on the frame'members 16 and 17 intermediate'the box-shaped frame and the vehicle a. vertically disposed plate or snow board 32 which is secured, as shown at 33 and 34, to the'members 16 and 17. The plate or board 32 carries at its lower end brackets 35, to which are secured caster rollers 36 whichaid in supporting the attachment.

' The box-shaped frame has rotatably mounted at its ends a pair of shafts 40 and'41, on the 46 carried by the hub 47 'of a cone-clutch member 48 rotatably mounted on a shaft 49. The

shaft 49 also' has mounted thereon and se-v cured thereto a cone-clutch'member 50 adapted to co-act with the clutch member 48. A casing 51 is secured to the plate 32 and encloses the clutch mechanism.

The shaft 49is connected through a universal joint 53 to the front end 54 of an extension of the power shaft of the vehicle 10. It will be noted that the universal vjoint 53 is substantially in alignment with the pivots 14 and 15 of the frame members 16 and 17, 'thus permitting the frame members to'jbe. tilted without interfering with the driving connection. Y i i The clutch member 50 has connected thereto a lever 55, which is operated by a rod 56 which will be extended rearwardly in position to be manipulata-d by the driver ofthe vehicle. The snow removing devices are carried by CTI the chains 88 and 39 consist of a plurality of cross slats y60. Each of the slats has a pair of lugs 6l and 62 extending laterally from each end thereof, and these lugs are mounted on pins 63. The pins 63 form the connections Vbetween adjacent links of the chain and lare extended endwise as shown in Fig. 6 to receive the lugs 61 and 62.v The upper strands rof 'the chains preferably are supported by plates 57 and58 attached to the topframe 2l (see Fig). y

Each of the slats also is connected to vtwo chains by means vof struts 65 and 66, these struts also being connected to link pins 63 of :the chain and being pivoted to the slats at 67 path of the vehicle in the direction of the arrow shown in Fig. 2. The slats will engage and draw thev snow across the path of the vehicle, discharging vthe snow at the right hand side of the path of movement of the vehicle. In this way the snow -will bequickly `and expeditiously removed, and it will .be

evident from the construction of the device that it can be easily and quickly attached'to and removed from a motor vehicle.

Y Although one specific embodiment of the in-V vention has been particularly shown and described, it will be 'evident that the invention K' is capable of modification, and that modifications and changes in the construction and in the arrangements of the various co-operating lparts may be made without departing from the spirit or scope of the invention Vas expressed in the following claims.

I claim- Y l. A snow removinv device, comprising frame members extending forwardly in a longitudinal direction from the .body of a motor vehicle, a pair offvertical posts secured and supported on Vsaid frame member at the front of the vehicle, a box-like frame of which said posts constitute a part thereof supported on saidframe members with said frame extending transversely of the vehicle along the front of it, an endless conveyorxmounted on said frame and substantially surrounding it and having slats across it for moving the snow` fromthe ground below the frame.

2. A snow removing device, comprising frame members, means for pivotally attaching said frame members to the frame of a motor vehicle, vertical posts secured to and supported on said frame members, Va box-like frame carrying said posts and Vextending transversely of thel frame members, sprocket wheelsmounted on said transverse frame at the ends thereof, endless chains mounted on said sprocket wheels, means for driving said chains, and cross slats secured to and adapted to'travel with said chains, said endless chains surrounding and enclosing said boxlike frame. Y

3.
